(Other stories by Michael J. Hammel)
"The original Gimp came with a wealth of effects filters, and the upcoming 1.2 release will certainly follow that tradition. Among the many features provided are the Blur filters. These filters provide various means of blending nearby pixels. The results vary according to the methods used, various seed values, and even with the type of image with which you are working."
"In this tutorial I'm going to cover each of the 7 blur filters that will be provided with the 1.2 release. If you've already started to experiment with this version you'll have no problem following along. If you're still using the 1.0 version you can still follow along - just ignore the filters which are not in your release. The others should be essentially the same."
"Note that all the blur filters only work on either RGB or Grayscale images. If you want to use the blurs on Indexed images you'll need to convert them to RGB or Grayscale first, using the Image->Modes options in 1.2 (or simply under the Image options in 1.0). Most blur filters will work on a selection or a complete layer, though in 1.2 there are exceptions which will be noted in the discussion."
